I considered making it a special mode of "git blame" when blame is fed a

all (nor do I think they need to be; blame-tree is _way_ simpler). And I

git blame dir/file.c
  "Show what revision and author last modified each line of a file"

git blame dir/
  "Show what revision and author last modified each file"

This makes sense to me (the user).
I don't understand the implementation thing. I don't see a difference between
those two commands. Even more, if I'm educated  Unix user I might know
directories are also files.

didn't want to steal that concept in case somebody can think of a more
content-level way of blaming a whole tree that makes sense (obviously
just showing the concatenation of the blames of each file is one way,
but I don't know how useful that would be). If we want to go that way,
we can always catch the special case in blame and just exec blame-tree.

Still can be in git-blame command, no?

The initial set of interesting files we come up with is gotten by
looking at the tree of the first pending object after parsing the rev
options (defaulting to HEAD). Which sounds a little flaky to me, but
does what you want in practice. I'd be curious if somebody can come up
with a counterexample where the ability to manually specify the source
tree would be more useful.

Same argument as for normal blame: I want to know who modified files at
the state of commit X (if I understand the question correctly).
